A display device comprises a pair of opposed soda-lime glass substrates. A chemically reinforced layer having a thickness of 20 &mgr;m or less is disposed on the surface of at least one of the opposing soda-lime glass substrates. An electrode is disposed on opposed surfaces of the soda-lime glass substrates, and a display material is disposed between the pair of opposing soda-lime glass substrates.

Display device and method of manufacturing the same

In a display device in which glass substrates are pasted together and a display material is filled therebetween and a method of manufacturing the same, provided is a display device composed of soda glass chemically strengthened by substituting atoms having an ionic radius larger than that of sodium atoms for sodium atoms on the surfaces of the glass substrates, and a method of manufacturing a display device wherein a chemical strengthening is carried out by dipping a soda glass substrate or a cell for the display device manufactured by using the substrate in a solution or a molten solution of a salt including cations having an ionic radius larger than that of sodium atoms.
